International Comfort Products GDL075N12A1 Thermistor
A thermistor is a specific kind of resistor whose rated resistance depends on the amount of, or lack thereof, heat. The furnace or AC deciphers the temp in certain areas to make a decision on what needs to be done. They tell the main board when a temperature reaches a certain point.
Elements of an ailing thermister
- The blower fails in the attempt to ramp up the airflow
- The entire system may not function depending on which is the damaged thermistor
